This study investigates the asymmetric interdependence between geopolitical risk (GPR) and the stock markets of the top-seven emerging (E7) countries (i.e., Mexico, Russia, Turkey, India, China, Indonesia, and Brazil) in the ongoing geopolitical conflict between Russia and Ukraine. With daily datasets covering the period 01-Feb-2022 to 25-July-2022, the squared wavelet coherence (SWC) and wavelet coherence phase difference (WCPD) techniques are employed. The results underscore heterogeneous and asymmetric market-specific coherence and lead-lag patterns regarding E7 stocks' interdependence with geopolitical risk. The findings imply high comovements between Black Swan events like the Russian-Ukrainian conflict and financial markets' volatility, highlighting the essence of alternative assets or asset classes for hedging geopolitical risks in the ongoing military actions. The heterogeneous and asymmetric responses offered by E7 stocks against GPR render emerging markets equities suitable for diversification and downside hedging strategies against GPR-induced shocks. The findings are robust to the time-varying parameter vector autoregression (TVP-VAR) connectedness approach. The results' implications for portfolio managers, investors, and policymakers are discussed.
本研究调查了在俄罗斯与乌克兰持续的地缘政治冲突中,地缘政治风险(GPR)与七大新兴(E7)国家(即墨西哥、俄罗斯、土耳其、印度、中国、印度尼西亚和巴西)股票市场之间的不对称相互依存关系。利用涵盖2022年2月1日至2022年7月25日期间的每日数据集,采用了平方小波相干(SWC)和小波相干相位差(WCPD)技术。结果强调了E7股票与地缘政治风险相互依存关系中存在的异质性和特定市场的不对称相干性以及领先-滞后模式。研究结果表明,俄乌冲突等黑天鹅事件与金融市场波动之间存在高度的共同变动,凸显了在当前军事行动中用于对冲地缘政治风险的另类资产或资产类别的重要性。E7股票对GPR的异质性和不对称反应使新兴市场股票适合用于针对GPR引发的冲击进行多元化和下行对冲策略。研究结果对时变参数向量自回归(TVP-VAR)连通性方法具有稳健性。讨论了研究结果对投资组合经理、投资者和政策制定者的启示。
